Abstract

The vacuum cleaner has a hollow first fixing member formed together with a body, and a second fixing member assembled with the first fixing member. The first and the second fixing members are formed with a first and a second ribs respectively. The first and the second ribs form a circular-shaped supporting rib part when the first and the second fixing members are assembled with each other. A rotational shaft of a wheel is inserted into the supporting rib part to be assembled therewith. Thus a port for fixing the wheel need not be formed on the body, and the air drawn into the body is not discharged through such a port. Further, since the rotational shaft does not protrude into the body, it is easier to install components in the body and to disassemble the wheel from the body.

Claims

1. A vacuum cleaner comprising:

a body for accommodating mechanical devices;

a first fixing member being mounted at one side of said body, said first fixing member having a hollow part, said first fixing member of which said one side forms a caved part along a planar direction thereof to be substantially U-shaped, a first rib which is substantially U-shaped protrudes outward at an edge of said caved part;

a second fixing member having a pair of arms protruding from a side of the second fixing member in parallel with each other, said arms being assembled by insertion with said hollow part of said first fixing member, a second rib which is substantially semicircle-shaped protrudes, said second rib for forming a substantially circle-shaped supporting rib part together with said first rib by an assembly with said first fixing member;

a wheel having a rotational shaft being inserted into said supporting rib part, said rotational shaft supported by said supporting rib part; and

a hooking rib protruding at one end of said rotational shaft, said hooking rib being placed in said hollow part of said first fixing member when said rotational shaft is inserted into said supporting rib part, whereby detachment of said rotational shaft from said supporting rib part is prevented.

2. The vacuum cleaner as claimed in claim 1, wherein said first fixing member is assembled with said second fixing member by an assembly of hooking protrusions protruding respectively at both ends of said arms and hooking holes formed at said first fixing member.

3. The vacuum cleaner as claimed in claim 1, wherein said first fixing member and said body are formed together in a body.
